4 RAM sticks will make my system slowere?

I was talking with a friend of mine today, about my future build-my-self gaming PC.

I said I was gonna buy 4GB (4x1024)Crucial Ballistix Dual Channel 2048MB PC8500 DDR2 1066MHz Memory (2 x 1024MB)http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=3116812&Sku=C19-6012 (Your welcome to come with better RAM alternatives, as long as theyr found on that side )

He then told me that having 4 sticks would cause my system to run slowere, can anyone in here confirm or disconfirm that statement?

It does depend on the application, for instance are you doing Cad or vid rendering? Gaming Vista..?
For a new vista system used for gaming, that may be a tossup, get a testing freeware and see by adding two chips and doing side by side tests.. For xp gaming rigs commen thought and experince is two gigs are enough and four slows down performance. Is it all about software? No, but the apps that need big memory definately do recieve a benifit to their speed using more ram, rendering, cad etc.

tests.. try ati tool, on my sys runnig this gives me a real time frames per second in the corner.. it may work with your video card.. free from this sight too!/ test at two and at four.. or simply use a benchmarking program, also free...

Well it can have a negative effect on your command rate . Usually you use 1T with 2 sticks of ram and 2T with 4 sticks, i generally found the bandwidth difference to be around 800MB\s+ between 1T and 2T command rates. Use Progs like Everest to see if theres really much of a difference.

The command rate doesn't have that much of an effect on DDR2. If you mean DDR then yes I would agree with you.
